NALCO 73385 is a high-performance, non-oxidizing biocide . While we often think of chlorine (an oxidizer) for cleaning water, non-oxidizing biocides like 73385 work differently—they disrupt the metabolic processes of microorganisms rather than just "burning" them away. Broad-Spectrum Efficacy : It is a "one-stop shop" for killing everything from slime-forming bacteria to stubborn sulfate-reducing bacteria (SRB), which are notorious for causing "pitting" corrosion in metal pipes. Specialized for "Closed Loops" : It is the preferred choice for closed-loop cooling systems and recirculating towers because it stays effective even when the water has a high pH, where other chemicals might fail. Physical & Chemical "Fingerprint" According to its technical specifications, NALCO 73385 has a distinct set of characteristics: Appearance : A colorless to yellow liquid. Scent : It has a "pungent" or "sweet" odor. Solubility : It is completely soluble in water, allowing it to mix instantly into industrial systems. Stability : It is non-flammable and stable under normal conditions, though it must be protected from freezing (it freezes at approximately -1∘Cnegative 1 raised to the composed with power C -21∘Cnegative 21 raised to the composed with power C depending on the specific formulation batch). Safety & "MSDS Verified" Precautions Because it is designed to kill microorganisms, it requires careful handling by humans. Verified safety data emphasizes the following: Skin & Eye Contact : It is classified as a potential irritant. Prolonged contact can cause tissue damage or severe irritation. Protective Gear : Handling requires chemical-resistant gloves , safety goggles , and standard protective clothing. Environmental Impact : It is often regulated as a Marine Pollutant in large quantities, meaning it cannot be dumped into sewers or natural water bodies without proper treatment. First Aid : If it touches the skin or eyes, the verified protocol is to rinse immediately with water for at least 15 minutes and seek medical advice. Regulatory Standing In the United States, this product is regulated under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and registered with the EPA. Interestingly, it is even certified as Kosher/Pareve for year-round use by the Chicago Rabbinical Council, which is a rare but vital certification for water used in food processing environments.
